I didn't buy my NX1s from Massdrop as lets be honest, you can get it at lower price with cheaper shipping if you look around.
Anyways, personal impression after using it for a few months, it's a beast. It doesn't sound really good when paired with a pair of hybrid IEMs like the Fender FXA7 or the Aurisonics ASG 2.0. Things will sound a bit lack lusting without the bass boost turned on and the soundstage seemed to be more compressed than without the NX1s (just a bit). However the improvement with the NX1s with IEMs and without is very noticeable still and it's not bad. And same goes with Dynamic Drivers only IEMs like the SE215 SE (blue) and the Audio Technica IM-50.
Interestingly, when paired with a pair of pure Amateur Divers IEMs like my friend's UM Pro 30, the difference is very significant. The NX1s is capable of bringing out more bass from the Pro 30, making it more balance sounding. And believe it or not, though it does not bring out the full potential, the NX1s is capable of powering and bring out more details from the monstrous SE846 without turning on high gain - at least much, much better than direct output from an iPhone in comparison.
As a whole, considering the low price and it coming in such small form factor, the NX1s is nice deal for me as I was looking for a portable amp to go with my iPhone. Battery life is also nice as I can go on for at least three to four days before plugging it into charge. (I typically listen to music for at least 3-4 hours per day and often forget to turn it off and kept it on without playing any music for an hour or two.)
Just some personal opinion to try and help out anyone considering this. Hope this helps! :)

ansonchcI have this amp as well (using it to power a pair of VE Monks at the moment!), and agree with a lot of your sentiments here. That being said, do you ever feel that some IEMs feel underpowered by the unit on the low-gain setting? I have some minor hearing loss from playing live music for a few years, so I like to ask for outside impressions to make sure it's not just my ears.

bioshockerlolYes I think so, for instance the SE846 I tried the past weekend gave me the exact feeling that low-gain is underpowering it still despite of the fact that it was already much better than a smartphone direct output. The high-gain setting will distort and lead to a loss in quality of audio though, so I never really turned on high-gain in any cases. I'll see if I can try the SE846 some time later with high-gain and give you a more certain answer! Cheers. :)

ansonchcAwesome, thanks! I agree that the high-gain setting can lead so some distortion in the highs, but it really depends on the IEM/Headphone. My Ultrasone Pro 2400's handle it fine, but on some IEMs it ruins the sound profile.
